M46.28 Osteomyelitis of vertebra, sacral and sacrococcygeal region

Name of the Condition

• Osteomyelitis of vertebra, sacral and sacrococcygeal region

Summary

Osteomyelitis of the vertebra, sacral, and sacrococcygeal region is an infection of the bones in the lower spine, including the sacrum and coccyx. The infection causes inflammation and can damage spinal structures, potentially affecting surrounding tissues or nerves.

Causes

The condition is most commonly caused by bacterial infections, often Staphylococcus aureus. It may also result from fungal infections or spread from a nearby infection or through the bloodstream from another part of the body.

Risk Factors

• Advanced age
• Diabetes
• Immune suppression (e.g., HIV/AIDS, cancer)
• Intravenous drug use
• Recent surgery or invasive procedures
• Existing infections

Symptoms

• Lower back or pelvic pain
• Fever
• Chills
• Weight loss
• Fatigue
• Neurological symptoms (if the infection affects nearby nerves)

Diagnosis

Diagnosing osteomyelitis of the vertebra, sacral, and sacrococcygeal region may involve blood tests to identify infection markers, imaging studies like MRI or CT scans for detailed views of the lower spine, and possibly a biopsy to identify the causative microorganism.

Treatment Options

Treatment typically includes antibiotics or antifungal medications to eradicate the infection. In severe cases, surgical intervention may be necessary to remove infected tissue or stabilize the spine.

Prognosis and Follow-Up

Prognosis depends on the severity of the infection, the patient’s overall health, and timely treatment. Follow-up care often includes monitoring for recurrence and managing any residual symptoms or complications.

Complications

• Spinal instability
• Nerve damage
• Chronic infection
• Abscess formation
• Spread of infection to other areas

Lifestyle & Prevention

• Maintain good hygiene to reduce infection risk.
• Manage chronic conditions like diabetes.
• Avoid intravenous drug use.
• Seek prompt treatment for infections, especially those near the spine.

When to Seek Professional Help

Consult a healthcare provider if you experience persistent lower back or pelvic pain, fever, or other symptoms of infection, especially if you have risk factors for osteomyelitis.

Tips for Medical Coders

When coding for osteomyelitis of the vertebra, sacral, and sacrococcygeal region (M46.28), ensure documentation specifies the involvement of the sacrum and coccyx. Verify that the diagnosis aligns with clinical findings and imaging results to support accurate coding.
